Dear Experts, I am in our new office trying to make the PCs part of the domain.  We are over a VPN trying to make the PCs part of the domain and we are getting "a domain controller for the domain cannot be contacted". The only interesting thing I can tell you is that we are over a L2L tunnel to the domain controller.

I try entering the local DNS from the remote site. I got the same message.

Is there a particular port that I might need to open in the firewall.

If I do a tracert  from the actual PC I get this result to the domain controller:

C:\Users\me>tracert 172.16.100.10

Tracing route to is-doamincontroller.is.ad [172.16.100.10]
over a maximum of 30 hops:

  1    <1 ms    <1 ms    <1 ms  172.16.19.2
  2   121 ms    36 ms    29 ms  10.255.255.17
  3    55 ms    29 ms   118 ms  domaincontroller.is.ad [172.16.100.10]

I don't know why it will not work....

Make sure the DC is accessible by name from the remote PC, not just IP.  If the name isn't resolving, you have a DNS issue.
